IMPRQVEMENT IN APPARATUS Fon Rnc'rrrYrNG ALcoHoLIc menons.

The Schedule referred to in thesev Letters .'Pat'ent andi'making part oi the same.

`To all whom it may concern.- l

Be it known that I, CHARLES LoUrs FLmscH- MANN, of Cincinnati, in the State of Ohio, have invented a new and improved Apparatus for Rectifying Alcoholic Liquors; and I do hereby declare that the followingis a full and exact description thereof; refer ence being had vto t-he accompanying drawing and to the letters vof referenccmarked thereon.

The nature of my invention consists in an appa-l ratus for passing alcoholic liquors through compressed charcoal, and `keeping the coal in a compact state by 'means ot' self-regulating pressure, and to force air or suitable gases through the coal, when saturated with volatile snlistances,`in order to revive-.its rectii'ying powers.

'.lo enable others skilled in the art to .make and use my invention, Iwill proceedto. describe its construction and operation. i

Iconstruct my' rectilying apparatus of wood or metal, cylindrical or square.

In the drawing;-

The letter A represents a-cylindrical vessel, which is open on the top and closed at the bottom.

The cylinder A is provided on the -top with'a broad flange, B, whichis bent somewhat upward.

'lhe cylinder 4is closed by means of a cover, C. This cover is kept in` its place by screw-s a c. It has in its center a stuffing-box, yb,intowhich tits .the piston c.

Ou the piston rests the lever d, which is secured .in

'the arms e, itstenedto'thc flange B.

The lever d is provided with a weiglit, j.

Inside of the cylinder, and below, is a false bottom, D, whichis placed four or more inches above the bottom of the cylinder A. The false bottom D has a num'- ber of holes, to letjthcliqnor pass np through the coal.

.On this false bottom is placed a woolen blanket, g, or some other stuff. Upon that is placed the char- `coal or other suitable `material for rectitying purposes. l The `coal E is packed 4into the `c vlimler with great care, and' made very compact.

When the coal reaches the'top of the cylinder another piece of' blanket, h, is spread over the coal, and upon that the tlte1plate F, which is provided with .'holes to allow the liquor to escape uplthrough the pipe vI, which empties into aproper receiver.

' When the cover C is secured the piston c is placed upon the filter-plate `F and the weight f adjusted. The coal is. thus compressed and held tight in its place, preventing it from being disturbed by the upward pressure of thc liquor, which maybe supplied from a very high point.

'lhe supply-'pipe G enters the cylinder near the bottom. It'is provided with a stop-cock, h. It communicates with the reservoir H, containing the liquor to be rectified.

The short pipe K communicates witht-he space L between thebottomof the cylinder A and false bot;

toni D. It is provifledlwitha stop-cock, 1'.. It has on its end a screw-tlnead, k, to receive a coupling-nut to connect a pump, as shown in the drawing by dotted lines. l

The flange B has a small opening, 1,' to allow the liquor which may accumulate to pass iu a proper receiver.

Operation.

The liquor to be rectified is put into the reservoir H, and, when the stop-cock h is opened, it'entersthe cylinder below, andpasscs np through the compressed coal and out through pipe I into a receiver.

When the coal gets saturated with essentialoils, etliers, acids, Sie., and when it loses its reetifying p'owers, the communication with the reservoir is stopped by closing the stop-cock h, and a pump is attached to the pipe K, and the liquor which has been absorbed by the coal is pumped liom it.

The coal may be washed by means of cold or warm water, or cleansed by common or surcharged steam, in

order to drive out all the volatile substances. When the coal is puriiied in that manner, the pump must be set iu motion' for a considerable space of time, to-

expel from the pores 'oi' the coal all 'vapors or moistnrc, and to impregnatel the coal with dry fi'esh air.

The coalregains in that way vagain its rectifyi'ng powers, and may be renewed every time the coal gets cloggedwith the essential oils, Sac.

Should the operationof rectif'ying be stopped 'for' Third, the apparatus being airtight, there is very little loss ily-evaporation, even ii' interrupted for any length of time.

Fourth, on' account ofthe small quantity of coal employed, the alcohol is easily abstracted from it again.

" Fifth, the coal can be revivitied in the apparatus without removing it, which ati'ords great economyin coal and labor.

\Vha.t I'claim as my invention, and desire to secure by Letters Patent, .is-

lhe sltregulating pressure upon the rectiiying nie-- dium by means of the lever d, weight f, piston c, and stuing-box l), substantially as described.

Also, the pipe I in the cover, in combina-tion with the induction-pipe Gand exhaust-pipe K, placed in the lower part ot' the chamber L. of the'vessel A, sub-- stantially as and for the purpose described.
